Local Environmental Conditions
oak and hornbeam are the dominant tree pollen source around Siófok, which sits on Lake Balaton's southern shore in Somogy; grass and cereal pollen from nearby farmland and parks builds through spring into early summer. The balance between green space and built-up ground shapes how exposure differs across the town.
Siófok follows a pattern typical of Somogy: hazel and alder first, then oak and hornbeam over the following weeks, then grass and cereal pollen into early summer, running February through September overall. the Pannonian plain's ragweed season runs unusually long, peaking from August into October.

How often is the Siófok pollen forecast updated?
The Siófok pollen forecast is updated four times daily. See the timestamp below for the most recent update.
Does pollen in Siófok come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Siófok based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Siófok, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
